I've been running the Terminator system on my supercharged 350 with a 4L80E transmission for over 6 months. Last month I changed transmission and the new transmission has one issue. If I am driving down the freeway cruising the TC will lockup and I get the indication on my display. Then I will press the accelerator and the display will show that the TC is unlocked, but the TC stays locked up even when I continue to press the accelerator even more to cause a downshift to third.

If I put on the brake the TC will unlock, and it stays unlocked when I come to a stop and does not stall or bog the engine. I've talked with the transmission builder and they are pointing to the controller and I say the old transmission was fine. The old transmission started slipping and I replaced it before anything else broke. Anyone have this problem before?
